Potential Side Effects of Chemotherapy Drugs
Patients with medulloblastoma frequently experience significant side effects from chemotherapy that impact their daily lives. Understanding these effects and their management is essential.
Toxicity is a major concern, as chemotherapy targets rapid-dividing cells but can also damage healthy ones, leading to side effects like nausea, vomiting, and bone marrow issues.
- Nausea and vomiting are common symptoms that can often be managed with specific medications.
- Bone marrow suppression leads to anemia, increased infections, and fatigue, and is typically managed with growth factor therapy.
- Temporary hair loss that can still be distressing for patients.
Managing adverse reactions involves careful monitoring and providing support. Regular blood checks can detect issues early, enabling prompt medical intervention.
Palliative care plays a crucial role in managing side effects by alleviating symptoms, providing emotional support, and improving quality of life during cancer treatment.
